Linux Distros Unpatched Vulnerability : CVE-2026-96889

critical Nessus Plugin ID 349587

Synopsis

The Linux/Unix host has one or more packages installed with a vulnerability that the vendor indicates will not be patched.

Description

The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available.

 - A flaw was found in librsvg. When processing an SVG document containing nested XML inclusions (Xincludes) with duplicate entity declarations, a use-after-free error can occur. This vulnerability arises because the library incorrectly frees an XML entity that is still in use by the parser. An attacker could potentially exploit this to cause a denial of service or execute arbitrary code. (CVE-2026-96889)

Note that Nessus relies on the presence of the package as reported by the vendor.

Solution

There is no known solution at this time.
